Family ANTHRIBIDZ. 
Ormiscus *, nov. gen. 
Rostrum very short, transverse, truncated in. front ; the mandi- 
bles rather prominent and sharply pointed. , 
Head shorter than broad, its vertex on the same plane with the 
rostrum. 
Eyes large, prominent, converging in front, and contracting the 
forehead to about-half the width of the head; emarginated 
SICIOW. . ff 
Antenne springing froma little round cayity immediately beneath 
the eye ; if extended backwards they would reach the posterior 
margin of the thorax, or extend perhaps slightly beyond that 
part; the joints most of them slender ; the first jomt nearly 
hidden ; the second thicker than the following six joints, and 
nearly globose; the third joimt slender and the longest, but 
shorter than the two following joints taken together ; the fourth 
to the eighth inclusive obconic, becoming successively shorter ; 
the three terminal joints dilated, closely joimed, and together 
forming an ovate club. 
Thorax rather broader than long ; contracted, and subtruncated 
in front, broadest near the posterior margin, and convex imthe 
transverse direction; with an obtuse ridge at’ the side, but.con- 
fined to the hinder part, anda curved transverse ridge behind ; 
this ridge is very distinet;;)in the mesial line of the: thorax it 
nearly touches the hinder margin, but from that part at ascends 
as it runs outwards, so that it is somewhat distant from the 
posterior angle; the hinder margin straight, and the posterior 
angles right angles. 
Scutellum very small. | 
Elytra rather broader than the thorax; short, subcylmdrical, 
rounded at the apex, and with the humeral angles obtuse: 
Legs moderate ; tarsi as long as the: tibie ; theifirst:and fourth 
joints long and nearly equal ; the second and third rdtlier short, 
the latter distinctly bilobed at the extremity; the lobes:equal. 
Ormiscus variegatus. Orm. ater flayvescenti-tomentosus ; capite tho- 
raceque rugosis ; elytris eneo-micantibus, indistincte punctato- 
striatis) pube alba; ‘flava et fusca variegatis ;/ posti¢e- macula fusea 
communi cordifermiz>singulo prope medium fascia obliqua ornato ; 
antenyis articulis basalibus ad basin, tibiisque flavescentibus ; ferno- 
ribus piceis, ad basin pallidioribus.—Long. corp. 1 lin. 
Var. f.: Elytris rufescentibus, marginibus maculaque transyersa prope 
medium nigrescentibus. 
* ‘Opuioxos, a small necklace, a collar. The little insect here described 
has a curved ridge crossing the back part of the thorax, a character not 
peculiar to it, but which is more distinct here than in most others of the 
Anthribide.
